Patented Sept. 27, 1932 UNITED STATES PATENT OFFICE i ECKLEY M. SIMMONS, OF RIDGEWOOD, NEW YORK METHOD AND MACHINE FOR CUTTING :AND FORMING PLATES ANDOTHFIR ARTICLES Application filedOctober 9, 1930. Serial No. 487,602. 7

One of the objects of the invention is to provide means for cutting sides of a plate or plates from a sheet of material and for subsequently cutting the remaining sides of the plateo'r plates, which permits the plate or plates to pass freely from the machine.

A further object of the invention is to arrange the cutting means so that as the sheet of material passes through the machine the forward part of the sheet of material is first cut to form sides of the plate or plates and the rear portionof'the sheet of material is subsequently cut to form the remaining sides of the plate or plates and to completely sevIer n this manner the blanks will be free to pass from the machine. The second cutting, which severs the blanks from the sheet of material,

7 does not cut the material at the front of in connection with the second cutting means so that the plate or plates will be formed by the dies as the blanks are severed from the sheet of material.

The invention furthermore has as an object to provide a cutting blade having ad jacent cutting edges, one edge serving to cut one side of a blank and the other edge serving to cut subsequently the other side of the blank.

Other objects' of the invention are to provide means to heat the dies, meansto wet the paper when acted on by the said dles, and means for gripping the blank as it is acted on by the dies.

Another object of the invention is to provide a method of cutting and forming plates in connection with which the machine may be used.

Additional objects of the invention will appear in the following specification in which the preferred form of the inventionv is described.

In the drawings similar reference characters refer to similar parts in all the views,

of which 7 Figure 1 is a sectional elevation illustrating the invention, the view being taken along the line 1-1 of Figure 3,

Figure 2 is a plan view illustrating the sheet of paper or other material as shown in'Figure 1 with certain of the blanks severed by the cutter and other of the blanks partially sevcredby the cutter.

Figure 3 is a plan view ofthe lower cutter member and the dies associated therewith,

Figure 4c is a plan view of the upper cutter member, I p

Figure 5 is a perspective viewillustr'ating the upper cutter member, and

Figure 6 is an enlarged perspective view illustrating a platewhich may be made by the method and machine which is the "subject matter of this application.

It will be understood that while the invention has been illustrated with particular reference to its use for manufacturing plates, the method and machine which are the .subject matter of this applicationmay "also be used to manufacture, not only plates, but cake circles or discs, milk bottle caps, ice cream dishes of various shapes, pan linings of various shapes and sizes, cake liners, butter dishes or chips, spoons, and other articles.

'By referring to the drawings it will be seen that asheet of paper. or other material 10 is fed b rollers 11, which may be rotated by any well 'nown means. The sheet of paper or other material is'fed by this means to the cutters and dies which will now bedescribed,

Aswill be seen by referring to F igurc'2 of the drawings, when the cutter is operated to make the firstcuts in the sheet of paper or other material, these cuts will be the cuts 12, 13 and 14 forming the outer sides of certain of the discs. WVhen the cutter is subsequently raised and lowered it will againcut the sheet of paper or other material to make the cuts 15, 16 and 17, these cuts 15, 16 and 17 being made between the cuts 12, 13 and 14 and the rollers 11, the cuts 15, 16 and 17 serving to completely sever the discs 18, 19 and 20 from the sheet of paper or othermaterial 10. The upper cutter member 21, which is illustrated in Figures 4 and 5 of the drawings, has cutting edges 22, 23 and 24 to make the cuts l2, 13

and 14 and at its other side cutting edges 25, 26 and 27 to make the cuts 15, 16 and 17, it being understood that the discs 18', 19 and 20 will be severed from the sheet of paper or other material 10 by the said two series of cuts. The upper cutter member 21 cooperates with the lower cutter member 28, which has a cuttin edge 29for, cooperating withthe cut.- ting e ge 22, a cutting edge30 for cooperating with the cutting edge 23 and a cutting edge 31 for cooperating withthecutting edge 24, the lower cutter member 28 also has a cutting edge 32for cooperating with the cutt-ing edge 25, a cutting edge 33 for cooperating with the cutting edge 26 and a cutting edge 34 for cooperatlng withthe cutting edge 27. Therefor,e,,as the sheetofpaperor other materiallO passes through the machine, it is first cut by the cutting edges .22, 29, 2,3, 30, 24 and31 to make the cuts 12,13 and 14;and,is subsequent.- ly. cutby. the cuttingedges 25., 32, 26, 33, 27 andl34to makethecuts 15, 16 and17, thereby forming the discs 18, 19. and 20.

The upper cutter member:21:is mounted on a basev 35 which, has. bearings 36 through which, guide members 37 are disposed, these guide members 37 being mounted on abase 38 towhich asupport 39,, is secured, the lower cutter member 28 being securedto the said support. 39. There is also secured' to the base 38 a die, 40,,thedie40 having an opening 41 in,W.hiCh a: gripping plate 42; is disposed, the gripping plate 42-.being heldyieldingly up: wardbymeansofthe springs .43., There is also an opening;44.in.thegrippingplate 42 andan opening 45, in .the base. 38., in which .is is osed ajaw 46, the j aw 46 being held yiel dinglyin position .bymeans of aspring47. Thedie =40,.ooo.perates ,withadie 48 which is secnredito a support49, which .in turn .is .securedito theha-se35. The die 48 andith'e sup p0rt49. have openings 5,0 and 51 inwhich a jaw 52 is disposed, the jaw 52 being positioned 01. cooperating with, the jaw. '46 and being 5.3... 11 Will hevunderstood that the die. 48 with its jaw 52 Willdescend with the upper. cutter member 2.1,andjthatas the. cuts 15, 16 and .17.

as, means ,forn heating the dies 40 and 48;

which ,amedisposed in .close proximity to the openings 54, but it will be understood that any otherfdesired means may be employed to heat-thesaiddies 40 and 48. It is'also. advantageous to wetthe blanks 18, 19'and'20 as they are about to be'formed in shape by means ofjth'e. dies40'iand 48 and any desiredmeans heldyieldingly,extendedib'y means of a spring may be employed to wet these blanks such as the outlets 55 leading from a container 56.

As shown in the drawings the upward movement of the gripping plate 42 is limited by the shoulders 55 and the movement of the jaws 46 and 52 is limited by the shoulders 56.
